Hi

 

A question for all you auto electricians out there, I have got a Boost gauge with a boost nipple out the back and 3 wires Black, Red, White, Instructions say connect Black to earth, Red to ACC (ignition accessory feed) and the White to the pos (+) of the battery.

 

When i wired it up i only had ground and Acc feeds so i wired up the red and white together

 

My one complaint to the supplier was that although i could now see the outer gauge numbers, i could not see the needle. they then sent me the instructions and said "have you wired it up correctly" obviously i hadn't so i spent today re-wiring it, However still no needle illumination, thats another story..

 

My questions is what is the need for the white lead, it obviously has ought to do with the needle illumination

 

So why have it, it still illuminates without it?

 

Regards

Is it a colour changing gauge as the perm live wire is there for the memory to save a re-cycle of the colours everytime you start the car...does that make sense..lol

Yeah it is.. might be right there..,
